In the November issue of Good Housekeeping (excerpted via the Daily Mail), the 42-year-old "Mike & Molly" star speaks candidly about her struggle to lose weight. "Sometimes I wish I were just magically a size 6, and I never had to give it a single thought. But I am weirdly healthy, so I don't beat myself up about it -- it wouldn't help, and I don't want to pass that on to my girls." (McCarthy and her actor husband, Ben Falcone, are parents to daughters Vivian, 5, and Georgette, 2.)

Because she regularly plays tennis and does Pilates, McCarthy is dumbfounded as to why she hasn't slimmed down. "I don't really know why I'm not thinner than I am," the "Bridesmaids" actress says. "I don't really drink soda, I don't have a sweet tooth and we eat healthfully at home."

McCarthy knows she's not the only woman who is unhappy with her body. "Pretty much everyone I know, no matter what size, is trying some system," she tells the magazine. "Even when someone gets to looking like she should be so proud of herself, instead she's like, 'I could be another three pounds less; I could be a little taller and have bigger lips.' Where does it end?"

According to McCarthy, she's learned to make peace with her body by focusing on the positive. "You just have to say, 'It's pretty damn good. I am right here at the moment and I'm OK with it. I've got other things to think about.'"
